Abstract

This invention relates to a method for producing a decorative reflective surface covering with improved adhesion of the various layers, having a backing, metallic areas and a transparent top layer, and the product thus produced. This product is produced by applying an adhesive on the surface of a backing in regular, spaced intervals, bringing a metal face of a film in contact with the adhesive to secure it to the backing, removing the metal film whereby the areas in contact with the adhesive remain on the backing and then applying a transparent layer to the surface of the backing covering the remaining metallic areas.

Claims

1. A method for processing a decorative surface covering having a metallic appearance which comprises coating a backing sheet with a first resinous composition layer, heating to solidify the coating, applying an adhesive in the form of spaced apart discrete dots, squares, or other shapes on the surface of the solidified coating, laminating a metallic film to the adhesive coated surface, adhering the metallic film to the adhesive, removing the portions of the metallic film not adhering to the adhesive, and applying a transparent or translucent second resinous composition wear layer to said first resinous layer, covering the metal film adhered to the adhesive as well as the unmetalized areas.

2. The method of claim 1 wherein a design is printed on the surface of the metallic film.

3. The method of claim 1 wherein said metallic film is a metalized film of polyethylene terephthalate.

4. The method of claim 3 wherein said polyethylene terephthalate film is approximately 0.0005 to about 0.005 inch in thickness and said metallic film is approximately 1 to about 10 microns in thickness.

5. The method of claim 3 wherein said adhesive is applied by a rotogravure printing roll.

6. The method according to claim 5, wherein said adhesive layer is applied in the form of a design.

7. The method according to claim 6, wherein said adhesive layer is applied to the surface of the metal film contacting said first resinous composition.
